Last week, Washington Post staffers raced each other by car and public transportation along several typical commuter routes. Today's report compares commuting by car and by bus and subway from the Takoma Park nieghborhood near Walter Reed Hospital in the District of Columbia to the Rosslyn high-rise office center in Arlington.

Start: 8:02 a.m. at Georgia Avenue and Piney Branch Road NW.

Finish: The Metro subway station elevator on North Moore Street in the middle of Rosslyn.

Bus and Subway: 31 minutes.

Car: 38 minutes. Car

I drove south down 13th Street NW, which has four lanes heading one way toward downtown during the morning rush hour. Traffic moved smoothly as some drivers exceeded the 30 miel-per-hour speed limit.

Reaching Logan Circle, I manevuered onto 19th Street NW, where, heading south, I encountered my first traffic backup, cause by a double-parked taxi. At E Street NW I turned west, went over the Theodore Roosevelt Bridge and made my way to Rosslyn Circle was still relatively light.

Then I hit my second big delay - parking. The all-day lot for commuters at 19th and North Moore Streets in Rosslyn was about half full, but it seemed to take the attendant forever to show me where to park and to make change (cost: $2.50). After walking a half block, I made it to the Metro station elevator at 8:40 a.m.
